4 Technology Overview

Use GPTT Act (Glycine-PEG-Trizol-oligodT) viral RNA was extracted shellfish samples or nano-beads; independently selected from Take astrovirus capsid protein coding gene (ORF2) 5 'end, GⅠ type and GⅡ highly conserved type norovirus virus ORF1 and ORF2 joints Shou sequence design 5 ~ 6 RT-LAMP primers, eight separate areas 7 ~ specifically recognizes viral RNA on having a chain set In other action Bst enzyme, under AMV reverse transcriptase action at isothermal conditions (63 ℃ or 65 ℃) insulation 60min, you can step to achieve the virus RNA amplification efficiency. Amplification reaction produces a large number of by-product (magnesium pyrophosphate) milky white precipitate formed, the reaction tube was added SYBR GreenⅠ fluorescent dyes, fluorescent green anode reaction was rather negative reaction is a fluorescent orange.
